Oi! I just noticed, that the screens from Tenchi Meidou and Vajura Fight have Key Factory (ケイ ファクトリー) credited in them, too!

So it's likely, that Kitty Films only worked on DERB and none of the other games. (still, we are going to credit them on the KDZGG page, too, cause we dunno, if KF means Kitty Films or Key Factory in this case)
